Based on the information provided, it seems that you are asking about the total magnification of a microscope and some details about its components and usage. Let me provide you with the answers to your questions:1. Total magnification of the scanning lens (40x):The total magnification of a microscope is calculated by multiplying the magnification of the objective lens (scanning lens in this case) by the magnification of the eyepiece lens. Typically, the eyepiece lens has a magnification of 10x. Therefore, the total magnification would be 40x (objective lens) x 10x (eyepiece lens) = 400x.2. Knob for physically moving the stage up and down (course adjustment):The knob used to physically move the stage up and down is called the coarse adjustment knob. It is used for making large adjustments to the focus of the specimen.3. Knob for enhancing the clarity of the specimen (fine adjustment):The knob used to enhance the clarity of the specimen and make the image more crisp is called the fine adjustment knob. It is used for making small adjustments to the focus after using the coarse adjustment knob.4. Direction of the microscope arm when placing it on the desk:When placing a microscope on your desk, the arm should face away from your belly. This helps to keep the microscope stable and prevents it from tipping over.5. Type of microscope used in the laboratory (bright field):The type of microscope mentioned in the question is a bright field microscope. Bright field microscopy is a common technique used in many laboratories for viewing stained or naturally pigmented specimens.
